First of all, we distinguish representation (the capacity to act on behalf of a third party, art.5 Law 39/2015) from registration in the REA (a means of proving representation, art.6 Law 39/2015).

Any power of attorney registered in Representa is cancelled through waiver, revocation or expiration, as it refers to the registration regardless of whether the registration was with or without validation (in the NTI project the reason field, in the case of waivers and revocations, is optional).

That is, the cancellation of a registration in Representa does not necessarily affect the ability to act on behalf of a third party if, for example, when carrying out the procedure, the current powers of attorney are attached or a representative certificate is used.

In the event that a representative makes a request, by virtue of a previously revoked representation registered based on the validation of legal documentation, and does not accredit this representation (or not sufficiently), the AAPP should require the amendment, not reject the procedure (art.5, section 3 in relation to section 6).

Therefore, to request cancellation from the REA, in this case from Representa, no special procedure or validation of the cancellation is required; the will of one of the parties is sufficient to cancel a registration.

Without prejudice to the fact that it is not legally provided for, the purpose of validation is to verify the capacity to act on behalf of another (that it is really a type A power of attorney, if there is any limitation due to the amount, etc.); in the case of withdrawals, whether by resignation or revocation, what prevails is the will of the person making the request.
